Estimation and Reproducibility Issues in ECG Signal Monitoring. A Simulation Study

Two Important issues of ECG telemonitoring are addressed by statistical modeling. The first one is related to the reproducibility due to inaccurate electrode replacements, the second one is due to inadequate signal estimations if only a limited number of leads are recorded instead of the complete 12-lead system and the unmeasured leads are estimated. The required data of the simulation were extracted from a database of body surface potential maps with 192 leads. The error terms were represented by correlation coefficients, RMS error histograms and Box and Whisker diagrams. The monitoring by I, II, and V2 leads is presented in depth.
